Which option does a Cisco UCS B-Series half width blade server support?

Half-width blade servers are designed for high density in a blade chassis and have limited physical space for internal components, commonly restricting local storage to a maximum of two drives.

While RAID 10 is a valid RAID level, it requires at least four drives to implement, which exceeds the typical maximum local drive capacity of a half-width blade server.

Blade servers utilize mezzanine cards for I/O expansion, not standard PCIe Fibre Channel adapters, which are typically designed for rack servers.

Blade servers are optimized for data center environments and high density, thus they generally omit integrated optical drives to save space, power, and reduce complexity.
